In telecommunications, broadband is a wide bandwidth data transmission with an ability to simultaneously transport multiple signals and traffic types. The medium can be coaxial cable, optical fiber, twisted pair, or wireless broadband (wireless broadband includes Mobile broadband). Voice, video, and data signals can be sent over a single broadband connection. Broadband connections allow people to access the Internet at high speeds. Various types of broadband connections include Cable Internet, Digital Subscriber Line (DSL), Satellite, Internet Calling, and FTTX.
Cable Internet access plans are available through cable television providers. The same cable line can be used for viewing television and accessing Internet. You can watch TV (Cable TV), talk on the phone, and surf the Internet simultaneously. Coaxial cables that transfer signals to your television also transfer data to and from your computer. You will need a cable modem, a router, Ethernet cards and routers to set up your home network.
Wireless Internet access does not require any cable. You do not even need a router for multiple users to access the same wireless service. With wireless Internet, the Internet Service Provider (ISP) sends the signal as a radio signal to a tower. This is similar to how a cell phone provider distributes signals. Many providers operate such towers, so wireless Internet is widely available.
Satellite is another form of broadband service that is used for high speed Internet access. You can choose this option when DSL, cable, or wireless services are not available in your area.Satellite Internet tends to cost more than other broadband Internet options.
A Digital Subscriber Line (DSL) connection provides high speed Internet access. You can access Internet using a phone line that is connected to a modem in the computer. DSL does not interfere with your telephone service, and you can use the telephone and access the Internet at the same time. Another advantage of using DSL for Internet connection is that you do not have to dial-up every time you want to connect to the Internet. Multiple users on your local area network (LAN) can access the Internet simultaneously.
Voice over Internet Protocol (VoIP) is a technology that provides phone services through your Internet connection. Voice is converted to a digital packet and is transmitted over Internet. When it reaches its destination, it is converted back to a regular telephone signal. With VoIP, you can call regular telephone numbers, and you can even use your standard telephone equipment. VoIP enables low cost International and nationwide calling plans.
Fiber to the X (FTTX) is a general term for any architecture that uses optical fiber instead of the usual copper wires for communication. There are different variations of FTTX that are classified on the basis of the use of fiber. The different types of FTTX include fiber-to-the-home (FTTH), fiber-to-the-curb (FTTC), fiber-to-the-node (FTTN), and fiber-to-the-premises (FTTP).
